Adrianb Posted October 11, 2020 Share Posted October 11, 2020 Hi all having fitted a new sump gasket I have now got a leak of oil,should I have done the bolts up to a certain torque I did not want to over tighten them and distort the cover!

glang Posted October 11, 2020 Share Posted October 11, 2020 Its not so much that the sump distorts but the area around the bolt holes gets dished as the bolts are tightened up over the years so the sealing is no longer uniform. The best thing is to flatten out the concave bits when the sump is off and make sure everything is smooth. Then use the correct spring washers and, as per the manual, torque to 16 -18ft.lbs (it is worth rechecking this from time to time as they do seem to loosen off). Did you use any sealing compound on the gasket? Quote Link to comment Share on other sites More sharing options...
Adrianb Posted October 11, 2020 Author Share Posted October 11, 2020 Hi,As I’m visually impaired I got someone to read the manual they obviously mist the important bit, thanks for the Info,I shall start again would I need to replace the gasket and apply a sealant?

glang Posted October 11, 2020 Share Posted October 11, 2020 In my workshop manual the bolt torques are listed at the begining for the whole car not in each section. First you could just check the bolt torques to see whether that stops the leak. If not Id remove the sump, inspect the gasket (either reuse or replace it) and then remount the sump once you've got it in good shape. I wouldnt be fussy about the sealant to use as its not a pressure joint so is just a back up to the gasket... Quote Link to comment Share on other sites More sharing options...

Pete Lewis Posted October 15, 2020 Share Posted October 15, 2020 do take care that bolts fitted to the front bearing sealing block do not bottom out its alloy and will strip easily im sure you will find some bolts are longer where they go through a reinforced flange and shorter in single skin the front block is a well known Oops !!! for failing/leaking if this happens you can tap 8mm metric , or drill and tap 3/8unf or buy a steel block from most suppliers to recover a striped block Pete Quote Link to comment Share on other sites More sharing options...
